Warhammer 40,000 Chainsword Build

Sometimes in the midst of a really big project, it's hard to stay motivated. In the fine-tuning stage, weeks can pass without really giving me something to brag about. When this happens, it's time to focus on a smaller tangent project.

This is one of those tangents:

This is the "chainsword," the melee weapon of choice from the Warhammer 40,000 universe. If a lightsaber was "an elegant weapon, from a more civilized time," the chainsword is the other thing. Big, ugly, and brutal, it exemplifies everything I've always liked about Warhammer 40K.

In a game where the Imperium of Man makes the "evil empire" of Star Wars look like something that belongs in Disneyland, the chainsword is a perfect fit. There's no notion of a kinder, gentler anything. It's simply made for carnage.

More pictures and a thorough description of how it was made after the jump.

Starting with a drawing photocopied from the Dark Angels Codex, my friend Matt and I took some measurements and cut out forms in MDF:

It was all I could do to fit them onto my forming table:

The parts were formed in .040" ABS plastic. The first pull came through alright, but there was some webbing between the pieces:

After rough-cutting the parts out of the formed sheets, I stacked them together to make sure they were adequately huge:

I also sculpted out a tooth for the chain:

Once I'd made a mold for the tooth, I went ahead and cast several copies:

Here they are laid up inside the blade:

Since I was going to need lots of them, I went ahead and made up a gang mold. Here they are all boxed up before I poured the rubber in:

I also designed some pieces to go into the hilt in order to make the bottom end stronger:

For the pommel, I whipped out this quick little sculpture:

As any WH40K fan knows, each additional skull makes the finished piece 12% more badass.

Here's the first set of parts coming together:

The perspective in that shot makes this thing look enormous. It is enormous, but not quite that enormous. Here's a better shot for scale:

The ridge along the spine is actually a piece of 1-1/2" ABS drain pipe cut in half lengthwise. Since I was using ABS sheet for the vacformed parts, I was able to use solvent cement to effectively weld the pieces together.

The resin cast details at the hilt had to be glued in with a cyanoacrylate adhesive:

As long as I was building a giant chainsaw sword, I figured I might as well incorporate some actual chainsaw parts. Specifically, I molded copies of the oil and fuel caps from an old dead chainsaw that my father had laying around:

The last thing the hilt needed was some faux machinery for the inside and another vacformed piece to tie together the grill vents:

Then all that was left was this little piece to close up the tip:

Here's the rough draft version all cobbled together:

Since I had the molds and a series of lessons learned along the way, I couldn't resist the urge to build a couple more. Here they are after I'd painted them in their base colors:

Here they are with a bit of weathering:

Adding in the teeth and a bit more weathering, they look like so:

The imperial eagle was cast from the molds I made back when I built the bolt gun.

The chainswords are still huge:

I'm very pleased with the end result:

Each one weighs in under six pounds, but they still look pretty damned heavy:

Here's a picture from earlier in the painting process showing some of the hilt details:

And a closeup showing the metallic finish on the teeth:

With the pair of them completely built and painted, everybody had to mess around with them. Here's a shot of Matt hamming it up:

Here's my friend Erin brandishing one of them:

All told, it was nine days between "Hey, I think we should build this" and "Wow, that was fun," and most of those days were spent working on other things. The important thing is that I got a chance to get something finished and feel good about my level of productivity.

Now it's time to get back to the main part of this project:
